glusterfs: failed to get the 'volume file' from server

You must provide the VOLUME NAME in the mount command, not the PATH.

If you are not using RPM packages it is possible you are experiencing this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1191176

The names of volfiles on disk was changed for improved rdma support. This change was introduced in 3.6.2.

stop glusterd, run glusterd --xlator-option *.upgrade=on -N to regenerate the volfiles, start glusterd (on all nodes).

I ran in to this issue today, I have ssl enabled for clients and servers. In my case I had not set the secure-access option on the client (making it use the glusterfs.ca file in /etc/ssl/)

To solve do this:

touch /var/lib/glusterd/secure-access
